[netdrvr] Remove long-unused bits from Becker template drivers

Symbols such as PCI_USES_IO, PCI_ADDR0, etc. originated from Donald
Becker's net driver template, but have been long unused.  Remove.

In a few drivers, this allows the further eliminate of the pci_flags (or
just plain flags) member in the template driver probe structure.

Most of this logic is simply open-coded in most drivers, since it never
changes.

Made a few other cleanups while I was in there, too:
* constify, __devinitdata several PCI ID tables
* replace table terminating entries such as "{0,}," and "{NULL},"
  with a more-clean "{ }".
